Hinge assembly for flat panel display appliance

Abstract

Disclosed is a hinge assembly capable of adjusting a tilting angle of a display in a display appliance. The hinge assembly includes a movable plate fixed to a rear side of the display and having a through-hole, a stationary plate coupled to a stand for the display appliance and having a through-hole, a hinge shaft passing through the through-holes of the movable and stationary plates and having a head portion, a coupling member fixed to one end of the hinge shaft, a first washer disposed between the head portion of the hinge shaft and the movable plate, first and secondary washers disposed at both sides of the through-hole of the movable plate, and third and fourth stationary washers disposed at both sides of the through-hole of the stationary plate. At least one of the first, second, third and fourth stationary washes is an elastic washer for applying compressive elasticity to the hinge shaft in an axial direction.

1. A hinge assembly for adjusting a tilting angle of a display for a flat panel display appliance, comprising:
 a movable plate fixed to a rear side of the display and having a through-hole; 
 a stationary plate coupled to a stand for the display appliance and having a through-hole; 
 a hinge shaft passing through the through-holes of the movable and stationary plates and having a head portion; 
 a coupling member fixed to one end of the hinge shaft; 
 a first washer disposed between the head portion of the hinge shaft and the movable plate; 
 first and second stationary washers disposed at both sides of the through-hole of the movable plate; and 
 third and fourth stationary washers disposed at both sides of the through-hole of the stationary plate, wherein at least one of the first, second, third and fourth stationary washers is an elastic washer for applying compressive elasticity to the hinge shaft in an axial direction and wherein the first, second, third and fourth stationary washers have at least one fixing boss, and the movable and stationary plates are formed with fixing holes adjacent the through-hole thereof for receiving the fixing bosses of the stationary washers. 
 
     
     
       2. A hinge assembly for adjusting a tilting angle of a display for a flat panel display appliance, comprising:
 a movable plate fixed to a rear side of the display and having a through-hole; 
 a stationary plate coupled to a stand for the display appliance and having a through-hole; 
 a hinge shaft passing through the through-holes of the movable and stationary plates and having a head portion; 
 a coupling member fixed to one end of the hinge shaft; 
 a first washer disposed between the head portion of the hinge shaft and the movable plate; 
 first and second stationary washers disposed at both sides of the through-hole of the movable plate; and 
 third and fourth stationary washers disposed at both sides of the through-hole of the stationary plate, wherein at least one of the first, second, third and fourth stationary washers is an elastic washer for applying compressive elasticity to the hinge shaft in an axial direction, and wherein the first washer is a flat washer, and wherein the first washer has an oil impregnating groove for preventing wear of a contacted portion between the washers and an adjacent component and for securing smooth pivoting movement. 
 
     
     
       3. A hinge assembly for adjusting a tilting angle of a display for a flat panel display appliance, comprising:
 a movable plate fixed to a rear side of the display and having a through-hole; 
 a stationary plate coupled to a stand for the display appliance and having a through-hole; 
 a hinge shaft passing through the through-holes of the movable and stationary plates and having a head portion; 
 a coupling member fixed to one end of the hinge shaft; 
 a first washer disposed between the head portion of the hinge shaft and the movable plate; 
 first and second stationary washers disposed at both sides of the through-hole of the movable plate; and 
 third and fourth stationary washers disposed at both sides of the through-hole of the stationary plate, wherein at least one of the first, second, third and fourth stationary washers is an elastic washer for applying compressive elasticity to the hinge shaft in an axial direction, wherein at least one of the stationary washers has an oil impregnating groove for preventing wear of a contacted portion between the washers and an adjacent component and for securing smooth pivoting movement.
